Don't bump your thread so quickly. It's unfair to the others that are asking for help.

CMD:unjail(playerid, params[])

    new id;
    if(PlayerInfo[playerid][pAdminLevel] < 4) return SendClientMessage(playerid,COLOR_GREY,"You are not allowed to use this command!");
    {
        if(sscanf(params, "u", id))SendClientMessage(playerid, COLOR_WHITE, "/unjail [PLAYERID]");
        else if (id == INVALID_PLAYER_ID) SendClientMessage(playerid, 0xFF0000AA, "Player not found");
        {
            SpawnPlayer(id);
            SendClientMessage(id,0xFF0000FF,"You have been unjailed by an admin.");
            new gName[MAX_PLAYER_NAME],string[128];
            GetPlayerName(playerid,gName,sizeof gName);
            format(string,sizeof string,"You Unjailed player %s",gName);
            SendClientMessage(playerid,0x00ff00ff,string);
        }
    }
    return 1;
}

Your code tried to unload the 'u' parameter in to playerid, so id would always equal 0, and the id would become playerid.
